No problem. But I need it a little smaller. scaling  - no matter if single axis or all 3 locked - no problem.\r\nBut: if i rotate the model  befor scaling  (it is vrtical in the project, so I rotate it so it can lay flat)  and then try to reduce i.e. the z-hight (just a prototyp - don't need all the material to be printed, only the perimeters), nothing is o.k.\r\nScaling all 3  dimensions (lock) is no problem.  Scaling a single axis is a little goofy...\r\nIt seems the rotating keeps the dimensions orientation, but the scaling don't really mind and is scaling the orientation, wich it \"thinks\", it might be the best... but not  the original  or the workspace orienation.\r\nIt seems to get a bit dizzy with the rotation befor scaling .\r\n![2017-11-05 3](https://user-images.githubusercontent.com/20270638/32417121-c6f4346a-c254-11e7-934e-9bf8133321ad.png)\r\n![2017-11-05](https://user-images.githubusercontent.com/20270638/32417122-c713ea80-c254-11e7-93a4-4a88a327bb3e.png)\r\n![2017-11-05 2](https://user-images.githubusercontent.com/20270638/32417123-c730c65a-c254-11e7-80b5-54830f960e82.png)\r\n\r\n\r\n\r\nNow i know, it's no problem to do the scaling first, then the rotation.

But then when you scale Z, it scales the **original** Z-axis, but @thjansen72 is expecting it to scale along the presently displayed Z-Axis, so that the shortest dimension (which is the _current_ Z) would be made larger.\r\n\r\nWhen all the rotations are 90˚, it's easy to adjust, but when you are rotating by some odd number, it gets tougher.\r\n\r\nKen - I think we had a similar discussion some time ago, but I can't remember if it was scaling or lay flat or something else (it may have been issuing a lay flat after rotating doing funny things?) I'd get something positioned, almost how I wanted it, then issue a command (lay flat?) and it would undo some of the rotations I had done."}}
